FMS6400 Description
The FMS6400 is a dual Y/C 5th order Butterworth lowpass video filter optimized for minimum overshoot and flat group delay. The device also contains a summing circuit to generate filtered posite video. In a typical application, the Y and C input signals from DACs are AC coupled into the filters.
